  1. 26. In-situ calibration device of firn properties for Askaryan neutrino detectors

    L2-uppsats, Uppsala universitet/Högenergifysik

    Författare :Jakob Beise; [2021]
    Nyckelord :Askaryan; UHE neutrinos; in-ice radio detection; in-situ detector calibration; deep learning; radio neutrino detector; ARIANNA;

    Sammanfattning : Simulations have demonstrated that high-energy neutrinos (E > 1017 eV) are detected cost-efficiently via the Askaryan effect in ice, where a particle cascade induced by the neutrino interaction produces coherent radio emission that can be picked up by antennas installed below the surface. A good knowledge of the near surface ice (aka firn) properties is required to reconstruct the neutrino properties. LÄS MER

  3. 27. Towards Vertexing Studies of Heavy Neutral Leptons with the Future Circular Collider at CERN

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Högenergifysik

    Författare :Rohini Sengupta; [2021]
    Nyckelord :Particle Physics; CERN; Future Circular Collider; FCC-ee; Heavy Neutral Leptons; Long-lived particles; Displaced signatures;

    Sammanfattning : Heavy Neutral Leptons (HNLs) are the heavier counterparts of the light neutrinos of the Standard Model of particle physics. HNLs can simultaneously solve several of the problems the Standard Model cannot yet resolve, one example being that they provide a candidate for Dark Matter. LÄS MER

  4. 28. Neutrino oscillations at the ESSnuSB experiment

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Hanna Wik; Kenny Andersson; [2021]
    Nyckelord :;

    Sammanfattning : This report aims to study the phenomenon of neutrino oscillations through derivation of the formulas for their transition probabilities in two flavors and expansions thereof in three flavors. By studying the series expansions of the transition probabilities in three flavors, one could get a clearer understanding of the effect of matter and the CP-violating phase, $\delta_{CP}$ on neutrino oscillations.

  5. 29. Investigations into neutrino flavor reconstruction from radio detector data using convolutional neural networks

    Kandidat-uppsats, Uppsala universitet/Högenergifysik

    Författare :Oscar Ericsson; [2021]
    Nyckelord :neutrino; neutrino flavor; flavor reconstruction; radio technique; deep learning; neural network;

    Sammanfattning : As the IceCube Neutrino Observatory seeks to expand its sensitivity to high PeV-EeV energies by means of the radio technique, the need for fast, efficient and reliable reconstruction methods to recover neutrino properties from radio detector data has emerged. The first recorded investigation into the possibilities of using a neural network based approach to flavor reconstruction is presented. LÄS MER

  7. 30. Neutrino Emission From Supernovae : At what distance will it kill you?

    L2-uppsats, Uppsala universitet/Högenergifysik

    Författare :Lukas Liland; [2020]
    Nyckelord :;

    Sammanfattning : A small report that investigates neutrino emission from supernovae, in order to estimate at what distance you will have to be from a supernova for the neutrino radiation to kill you. ... LÄS MER
